I assume this is the line I am looking for:

Deploying assemblies for a total size of 3304 bytes

This is in the Output window under the output from Micro Framework Device Deployment.

So what values should I be looking at in this output to determine where I'm at.

The very first number that it outputs:

Total: (11024 RAM - 91748 ROM - 50406 METADATA)

This would lead me to believe that I am over the 48KB of ROM data? But I assume this includes some of the assemblies. Is there a FAQ or a wiki that will help me understand this output?

Here is the code I ended up implementing for this.

The main function that was supplied by Hari that I modified.

        private static string ProcessRequest(string receivedStr)
        {
            //-- Parse the first line of the request: "GET /led/1 HTTP/1.1\r" --
            string firstLine = receivedStr.Substring(0, receivedStr.IndexOf('\n'));
            string sReturn = "Command executed at " + DateTime.Now.ToString();
            string[] words = firstLine.Split(' ');
            string[] parts = words[1].Split('/');
            string cmd = parts.Length > 1 ? parts[1] : "";
            string param1 = parts.Length > 2 ? parts[2] : "";
            string param2 = parts.Length > 3 ? parts[3] : "";
            bool bValue;

            bValue = param2 == "1" ? true : false;

            //-- Add more commands and param handling here --
            switch (cmd)
            {
                case "led13":
                    sReturn = ProcessOutputPort(led13, param1 ,ref bValue);
                    break;
                case "led12":
                    sReturn = ProcessOutputPort(led12, param1,ref bValue);
                    break;
                case "in0":
                    sReturn = ProcessInputPort(in0, param1,ref bValue);
                    break;
                case "in1":
                    sReturn = ProcessInputPort(in1, param1,ref bValue);
                    break;
                default:
                    sReturn = "Unknown Command at " + DateTime.Now.ToString();
                    break;
            }

            //-- Optional string to return to caller --
            return sReturn;
        }

The code to process InputPorts

        private static string ProcessInputPort(InputPort inport, string sAction,ref Boolean bValue )
        {
            string sreturn;
            switch (sAction)
            {
                case "state":
                    bValue = inport.Read();
                    sreturn = "Port is " + (bValue ? "On" : "Off");
                    break;
                default:
                    sreturn = "Unknown Parameter at " + DateTime.Now.ToString();
                    break;
            }
            return sreturn;
        }

And the code for the output ports

        private static string ProcessOutputPort(OutputPort outport, string sAction,ref Boolean bValue)
        {
            string sreturn;
            switch (sAction)
            {
                case "state":
                    bValue = outport.Read();
                    sreturn = "Port is " + (bValue ? "On" : "Off");
                    break;
                case "set":
                    outport.Write(bValue);
                    sreturn = "Port set to " + (bValue ? "On" : "Off");
                    break;
                default:
                    sreturn = "Unknown Parameter at " + DateTime.Now.ToString();
                    break;
            }
            return sreturn;
        }

Now I just need to make the changes to do something instead of just write back to the browser that I determined something.

Hi Yacko,

Welcome to the Netduino community.

One quick thought...you could create a collection of your InputPorts/OutputPorts along with a set of string identifiers...and then evaluate your input against that collection.

I had thought about that but I was having problems mixing inputport and outputport types in one collection and being able to use them in the same collection.

First I do love this code, although I would like to switch it to an interrupt based web server, but I'll get to that later. For learning how to use a simple web server this was a great example. I am trying to make a change to grab or change the value of an IO port based on the 3 values. I could write this with a ton of code and many objects but I'm sure there is a better way to do this I hope someone can point out.

Here are my static ports.

        static OutputPort led13 = new OutputPort(Pins.GPIO_PIN_D13, false);
        static OutputPort led12 = new OutputPort(Pins.GPIO_PIN_D12, false);
        static InputPort in0 = new InputPort(Pins.GPIO_PIN_D0, false, Port.ResistorMode.Disabled);
        static InputPort in1 = new InputPort(Pins.GPIO_PIN_D1, false, Port.ResistorMode.Disabled);

Here is a rough copy of the ProcessRequest function that I have been working on.

        private static string ProcessRequest(string receivedStr)
        {
            //-- Parse the first line of the request: "GET /led/1 HTTP/1.1\r" --
            string firstLine = receivedStr.Substring(0, receivedStr.IndexOf('\n'));
            string sReturn = "Command executed at " + DateTime.Now.ToString();
            string[] words = firstLine.Split(' ');
            string[] parts = words[1].Split('/');
            string cmd = parts.Length > 1 ? parts[1] : "";
            string param1 = parts.Length > 2 ? parts[2] : "";
            string param2 = parts.Length > 3 ? parts[3] : "";
            object selport;

            //-- Add more commands and param handling here --
            switch (cmd)
            {
                case "led13":
                    selport = (OutputPort) led13;
                case "led12":
                    selport = (OutputPort)led12;
                case "in0":
                    selport = (InputPort) in0;
                case "in1":
                    selport = (InputPort)in1;
                default:
                    sReturn = "Unknown Command at " + DateTime.Now.ToString();
                    break;
            }
            

            if (selport != null)
            {
                switch (param1)
                {
                    case "state":
                        if (selport.Read())
                            sReturn = "Led is On at " + DateTime.Now.ToString();
                        else
                            sReturn = "Led is Off at " + DateTime.Now.ToString();
                        break;
                    case "set":
                        if (typeof(selport) == typeof(InputPort))
                        {
                            selport.Write(param2 == "1");
                        }
                        break;
                    default:
                        sReturn = "Unknown Parameter at " + DateTime.Now.ToString();
                        break;
                }

            }


            //-- Optional string to return to caller --
            return sReturn;
        }

Is there an easier way to do this with mixed Input and Output ports?
